H manufactured by: ® Manufacturer: Maxtec, Inc European Representative Airox S.A. Parcd’activities Pau-Pyrenees L’echangeur BP833 64008 PAU Cedex France PREFACE This manual describes the function, operation and maintenance of the Maxtec Model OM-25ME and OM-25ME-L oxygen monitors. Notes are included where differences may occur between the two monitors. As members of Maxtec's MAXO2< line of oxygen analyzers and monitors, the OM-25ME utilizes the Maxtec MAX-250E oxygen sensor and is engineered for fast response, maximum reliability and stable performance. The OM-25ME is designed primarily for continuous monitoring of oxygen levels delivered by medical oxygen delivery equipment and respiratory care systems. Adjustable high and low level alarm setpoints make the OM-25ME ideal for use in neo-natal, anesthesia, and respiratory care. THANK YOU Thank you for your purchase of a Maxtec MAXO2< oxygen monitor. We appreciate the time and energy you invest in selecting the equipment best suited to your needs. As repayment, we are supplying you with a reliable, high-quality instrument that, with proper care and operation, will provide you with years of exceptional service. We also encourage your comments or suggestions as to how our equipment, in any way, can better serve your needs. Please feel free to write, FAX or e-mail us at the address on the back of this manual c/o the Maxtec Marketing Department. NOTE: In order to obtain optimum performance from your MAXO2< monitor, all operation and maintenance must be performed in accordance with this manual. Please read the manual thoroughly before using the monitor and do not attempt any repair or procedure that is not described herein. Maxtec cannot warrant any damage resulting from misuse, unauthorized repair or improper maintenance of the instrument. ! WARNING The sensor of the MAXO2 Oxygen Monitor (MAXO2) has been tested with various anesthesia gases including Nitrous oxide, Halothane, Isoflurane, Enflurane, Sevoflurane and Desflurane and found to have acceptable low interferance, the device in its entirety (including electronics) is not suitable for use in the presense of a flammable anesthetic mixture. Only the threaded sensor face, flow diverter, and “T” adapter may be allowed to contact such a gas mixture. To avoid explosion, do not operate the Oxygen monitor in the presence of flammable anesthetics or in an atmosphere of explosive gases. Operating the oxygen monitor in flammable or explosive atmospheres may result in fire or explosion. Never allow an excess length of cable near the patient’s head or neck, as such could result in strangulation. Secure excess cable to the bed rail or suitable object. Never use a MAXO2 monitor with a cable that appears worn, cracked or has damaged insulation Before use, all individuals who will be using the MAXO2 must become thoroughly familiar with the information contained in this Operation Manual. Strict adherance to the operating instructions is necessary for safe effective product performance. This product will perform only as designed if installed and operated in accordance with the manufacturer’s operating instructions. Use only genuine Maxtec accessories and replacement parts. Failure to do so may seriously impair the monitor’s performance. Repair or alteration of the MAXO2 beyond the scope of the maintenance instructions or by anyone other than an authorized Maxtec service person could cause the product to fail to perform as designed. Calibrate the MAXO2 weekly when in operation and if enviromental conditions change significantly. (ie, Temperature, Humidity, Barometric Pressure. --- Refer to Calibration section of this manual). Use of the MAXO2 near devices that generate electrical fields may cause erratic readings. If the MAXO2 is ever exposed to liquids (from spills or immersion) or to any other physical abuse, turn the instrument OFF and then ON. This will allow the unit to go through its self test and make sure everything is operating correctly. Never autoclave, immerse or expose the MAXO2 (including sensor) to high temperatures (>70oC). Never expose the device to pressure, irradiation vacuum, steam, or chemicals. To protect the unit from potential leaky battery damage always remove batteries when the unit is going to be stored (not in use for 1 month) and replace dead batteries with recognized name brand AA Alkaline batteries. The OM-25ME-L™ oxygen monitor has been manufactured with a low alarm setting adjustable down to 15% This change is within the guidelines set forth in ASTM Specification F1462-93. The OM-25ME-L™ is labeled to indicate this feature. Classification: Protection against electric shock: Internally powered equipment. Protection against water: Ordinary equipment Mode of Operation: Continuous Sterilization: See section 6 Safety of application in the presensence of a flammable aesthetic mixture: See section 8.1 FAILURE TO COMPLY WITH THESE WARNINGS AND CAUTIONS COULD RESULT IN INSTRUMENT DAMAGE AND POSSIBLY JEO...
